Hi,

May I ask you some questions? For 885 driver in cx23885-video.c,
in function buffer_queue(), what is the difference between q->queued
and q->active?

Also, you check if q->queued is NOT empty, then add to list. But
why do you add q->active to list when it's empty?

I'm learning how DMA and Risc works in cx23885 linux driver. Your
help is appreciated.

Thanks.
